A Pseudomonas fluorescens isolate (PF-1) resistant to carbapenems was recovered during an environmental survey performed with water from the Seine River (Paris). It expressed a novel Ambler class A carbapenemase, BIC-1, sharing 68 and 59% amino acid identities with beta-lactamases SFC-1 from Serratia fonticola and the plasmid-encoded KPC-2, respectively. beta-Lactamase BIC-1 hydrolyzed penicillins, carbapenems, and cephalosporins except ceftazidime and monobactams. The bla(BIC-1) gene was chromosomally located and was also identified in two other P. fluorescens strains isolated from the Seine River 3 months later.
一株抗碳青霉烯类抗生素的荧光假单胞菌（PF-1）是从塞纳河（巴黎）的水样环境调查中分离得到的。它表达了一种新型的 Ambler 类 A 碳青霉烯酶，BIC-1，与来自粘质沙雷氏菌的 SFC-1 及质粒编码的 KPC-2 分别具有 68%和 59%的氨基酸同一性。β-内酰胺酶 BIC-1 可水解青霉素类、碳青霉烯类和头孢菌素类抗生素，但不能水解头孢他啶和单环β-内酰胺类抗生素。bla（BIC-1）基因位于染色体上，3 个月后从塞纳河分离的另外两株荧光假单胞菌中也发现了该基因。
